John Little is considered “one of the top fitness researchers in North America” (Ironman magazine). He first learned of the principles of correct exercise from bodybuilding pioneer Mike Mentzer, when Little was 18-years old.

Little has authored no less than 12 books on exercise and another 38 books on philosophy (Eastern and Western), history and martial arts. A graduate from McMaster University, Hamilton, with a degree in philosophy, Little’s articles have been published in every major fitness and martial arts magazine in North America. Throughout his career, Little has worked alongside the biggest names in the industry, from Arnold Schwarzenegger and Mike Mentzer, to Steve Reeves, Lou Ferrigno and Jackie Chan.
